mounted on an'efiective cushioning device;

A furtherobject is to provide a seat adapt ed to function as a unit, under the resilient action of a centrally positioned cushionin device. Y

My invention consists. in a device for use in connectionwith a vehicle seat, and comtached to the floor ofthe. vehicle, a spring seated within the said pedestal, and aplunger engaging at its upper end with the said seat frame, and at its lower end with the said spring. Suitable braces are attached at their upperends 'to-the said seat frame, and at their lower ends to the lowerend of the plunger, where the latter enga es with the said spring. I also provide'rol er bearings located within said pedestal, and adapted to engagewith the sides'of the plunger in connection with its vertical movement; the parts being constructed and arranged all ashereiir after more particularly described in the ac companying drawing in which Fig. 1 shows a front elevation, partly in section, of a vehicle seat mounted on my cushioning device.

Fig. 2 is a side elevation, partly in section, of the same construction Fig. 1. I

Fig. 3 is an enlarged detail elevation, partly in section, of my edestal, showing the plun er, spring and r0 ler bearings, but havmg t e braces omitted.

Like characters of reference indicate corresponding parts of the difi'erent views.

10 is the tonneau frame of an automobile.

11 are the lateral structural beams of a chassis. 12 is a strong cross beam spanning the lateral'chassis beams and secured thereto by rivets 13. 14 is a hollow edestal, centrally mounted on the cross cam 12, and

I secured thereto by bolts 15. 16 are the an -lar and 17 the horizontal sections 0 V shaped brace members. Theangular sections 16 are securedby bolts 18 to a cross bar 19,

38 cut in the floor-of a car is made mte .the ang e irons 26, and to as illustrated in 1924. Serial no. lrisear.

l cross bar 19 is adapted to slide vertically '1n slots 21 suitably positioned in the walls. of the pedestal 14. Roller bearings 22 are located in the walls of the pedestal 14 and are so-pos1tioned as to engage the sides of the vertically slidable plunger 20. The lower part of the pedestal 14 encases a vertical coil spring 23- on which the cross bar 19 of the plunger 20 is mounted. The horizontal sec tions 17 of the V shaped brace members are secured by bolts v24 to a horizontal metallic plate 25 located centrally of the bench part of theseat frame work, and to the top of 1 the plunger 20. Angle iron supporting members 26 are secured by bolts 27 to theends of the brace members 17, at the point28, and form a rectangular frame within which rests the upholstered seat 29. Further lateral and back supporting members 30, 31, 31 32 and 32 secured to the angle irons 26 b bolts 33 serve to osition the seat inward y of the tonneau rame 10. The seat is thus so located as to be free to move in a substantially vertical plane under the actuation of the resilient device. The space 34 left between thev bracing members 30, 31, 31 32'and 32 and the tonneau frame 10 is enclosed from view when the seat is in place, by means of a flexible flap 35 secured to the tonneau frame '10 and to the to of the upholstered seat 29. When desira'b e a foot rest 36 mounted on a vertical member 37 extending through a. slog.

a with the other parts actuated by the resilient device b connecting members 39 secured to the vertical supporting member 37 f The above described cushioning device will, I believe, eliminate jars,,shocks and vibration which in' present automobiles are conveyed tothe bodies of passengers through the present t e of side upholstery and arm rests and bac cushlons all of whichare now fixed firmly to the body of the car.

Themobility of the vertical portions of the seat and suspension of the entire unit seat on springs gives to the vertical portions the same degree of resiliency thatthe present type of horizontal cushion possesses, and eliminates the shock and vibration conveyed by the vertical portions of the present type but not b' the horizontal part thereof because of t e suspension of the latter on resilient coil springs; The new device also avoids inching and jarrin caused by anlocated on the base of the plunger 20. Said tagonistic motions of vertica and horizontal portions ofthe seat. upholstery or cushions may be of the present standard type, with the omission or not as ma be desirable of the present coil springs un er the horizontal seat.

The drawings are of a rear seat. The device with slight variations can be applied to other seats as well and is intended to be so applied.

The foot-rest device is a matter which is not essential to the seat arrangement and may be dispensed with where not desired. It is advocated as an arrangement necessary to complete the general scheme, namely, to suspend on suitable, resilient springs all parts of the car which bear theipassengers weight, and to avoid contact of passengers bodies with parts of the car which are necessarily suspended on the heavy chassis springs only.

As the vertical portions of the seat will move up and down within the car body lhe construction of reraae'r with a hollow pedestal adapted to be secured to the floor of the vehicle and rovided withmain side slots and guide r0 ers iournalled in-supplemental slots, of'a seat, a plunger suitab y secured centrally to the bottom thereof and extending into the pedestal and between'the opposite rollers, a spring interposed between the bottom of the plunger and the bottom of the interior of the pedestal, a crossbar secured to the bottom of the plunger and extending outwardly through the main slots of the pedestal and braces connecting the crossbar at each end to each end of the seat.
